de letteratura » e letteratura, di letteratura, de litteratura
grunde liegen » zugrunde liegen, grunde gegen, zugrunde liegende
literatura de » literatura y, literatura en
liegen de » liegen die, liegen der, liegen bei
livre qui » livres qui, livre du
livre i » livro i, livre 1, livre sir

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( i grunde liegen de letteratura sarda ) OR ( i grand ((livre i) OR (livre qui)) literatura de )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grunde liegen de letteratura sarda ) or ( i grand ((livre i) OR (livre qui)) literatura de ))".
• Adding a wildcard symbol may retrieve word variants: (( i grunde liegen de letteratura sarda ) or ( i grand ((livre i) OR (livre qui)) literatura de ))*.
